Temperature, Species and Heat Transfer Characteristics of A 250 MWe Utility Boiler

摘要

This paper presents and discusses measurements of local flame temperature, local gas species concentrations and incident wall heat fluxes obtained in a 250 MWe residual fuel-oil front fired utility boiler. The work is aimed at improving knowledge of the efficiency of the thermal processes involved in large industrial boilers and covers three different operating conditions, which include load and air-fuel ratio variations.
